[ofa-general] Multiports single HCA uDAPL program problem

[Jie Cai]

Hi All,

I am kind of noob on IB and uDAPL program. Currently, I am trying to
write a program with multirail that utilizes 2 ports on a single Mallenox
ConnectX HCA on both nodes.

OFED1.3 has been installed on a SUSE 10.3 linux system.

The current problem is that IB connection via uDAPL are very unstable,
and sometime the connection can't be established.
Error message is usually like:

20350 Server waiting for connect request on port 45248
 accept: ERR dev(0x61d0e0!=0x61d0e0) or port mismatch(1!=2)
20350 Error dat_cr_accept: DAT_INTERNAL_ERROR
20350 Error connect_ep: DAT_INTERNAL_ERROR

The status of both port are active:
hca_id:    mlx4_0
    fw_ver:                2.3.000
    node_guid:            0003:ba00:0100:702c
    sys_image_guid:            0003:ba00:0100:702f
    vendor_id:            0x02c9
    vendor_part_id:            25418
    hw_ver:                0xA0
    board_id:            SUN0070000001
    phys_port_cnt:            2
        port:    1
            state:            PORT_ACTIVE (4)
            max_mtu:        2048 (4)
            active_mtu:        2048 (4)
            sm_lid:            10
            port_lid:        8
            port_lmc:        0x00

        port:    2
            state:            PORT_ACTIVE (4)
            max_mtu:        2048 (4)
            active_mtu:        2048 (4)
            sm_lid:            10
            port_lid:        9
            port_lmc:        0x00


I haven't done any specific configuration for multi-port. I assume that
OFED1.3 can do it automatically.

Would please any one help me on this?

Regards,
Jie
